Insights

Ischemic injuries after femoral artery catheterization are linked to vascular closure devices (VCDs). These injuries, often requiring complex repair, are more common in younger, female, and smoking patients using VCDs.

Area of Science:

  • Vascular Surgery
  • Interventional Cardiology
  • Medical Device Complications

Background:

  • Femoral artery catheterization is a common procedure.
  • Ischemic injuries are an uncommon complication.
  • Vascular closure devices (VCDs) are associated with these injuries.

Purpose of the Study:

  • To compare ischemic and hemorrhagic complications of femoral artery catheterization.
  • To identify factors associated with ischemic injuries.

Main Methods:

  • Retrospective review of operative registries from three hospitals (one academic, two community).
  • Inclusion of all femoral artery catheterization complications requiring operative intervention.
  • Comparison of demographic, clinical, procedural, operative, and outcome data between ischemic and hemorrhagic complication groups.

Main Results:

  • 95 patients required operative management for complications (40 ischemic, 55 hemorrhagic).
  • Ischemic complications were associated with younger age, smoking, VCD deployment, and female gender (controlling for VCD use).
  • Patients with ischemic complications had a significantly longer time to presentation.

Conclusions:

  • Ischemic complications following femoral artery catheterization are increasingly recognized.
  • Vascular surgeons must anticipate a shift towards complex arterial injuries, often related to VCD use.
  • Awareness of these specific risk factors can aid in prevention and management strategies.

Cardiac Catheterization I: Pre-Procedure Overview01:28

Cardiac Catheterization I: Pre-Procedure Overview

Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Cardiac Catheterization IV: Nursing Management

Nursing responsibilities before cardiac catheterization include:Assess for allergies and establish baseline health status.Before cardiac catheterization, assess the patient for allergies to contrast dye. Perform a comprehensive baseline assessment, including vital signs, heart and breath sounds, and a neurovascular assessment of the extremities, noting distal pulses, skin color, and temperature. Instruct the patient to fast for 8-12 hours before the procedure. Evaluate baseline laboratory...

Peripheral Artery Disease III: Interprofessional Care

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...
